L.S. up to vanilla kernel 4.7.3 I've seen no problems. On two different dekstops running vanilla kernel-4.8 I can force a crash by inserting an USB-modem that requires module cdc_acm.ko . (Strangely enough that doesn't happen on my laptop.) The moment that cdc_acm loads (manually or automatically - the hardware needs to be present) a kernel oops occurs. The system remains responsive for a while, but a reboot is necessairy. If you try a neat shutdown, the system will hang forever after 'remounting fs read-only'. You'll need a power-down. The oops tells things that I didn't all write down, but it says null pointer dereference at 00000246 ... failed while handling devices/pci0000:00/0000:00:1d.3/usb7/7-1/7-1:1d etc. ... udevd .. is taking too long.. Could someone please explain and repair the magic that is happening here?
